Dallas Assistant Chief Michael Genovesi, known as "Geno" around the department, will retire after Tuesday following more than 33 years with the department.

Genovesi, 56, said he enjoyed his job, which he called "a privilege," but had always intended to retire around that age.

In "honor" of his departure, Genovesi was given a cardboard cutout, signed by many officers, of Justin Bieber, who Deputy Chief Scott Walton insisted was Genovesi's idol.

"Since he is one of the Biebs' biggest fans, I thought he should have it," Walton said.

Genovesi said he didn't even know what Bieber looked like before Tuesday, but is now keenly aware after someone left the cutout sitting in his office.

He said Walton is likely his best friend on the department, which he implied was kind of sad.

"That describes my career -- when Walton is the best you can do," Genovesi said.

Walton retorted, "I’m the best friend he deserves."

On a more serious note, Walton said Genovesi will be missed.

"The man gave 33 years trying to help protect the city," he said. "He did it as an officer on the streets, but where he really excelled was leading others and using a common-sense approach to address issues. And he was always there with a quick joke and fast wit to encourage others."

For instance, Genovesi last year said of a new foot chase policy that if two or more suspects take off running, the officers there should both gang up and chase only one of them -- "preferably the fatter guy."

Genovesi, who most recently headed the patrol bureau, said patrol was always his favorite job, and his favorite rank remains police officer. He grew up in Connecticut and moved to Dallas to become a cop, a job he wanted since he was a teenager.

Genovesi said he will continue to live in Collin County with his wife Mary Lynn, to whom he has been married nearly 30 years. He said he will spend much of his time woodworking and travelling, but also plans to keep up with the department.

Meanwhile, with Genovesi's retirement, an assistant chief slot opens up. Chief David Brown stayed mum on his plans in an email Tuesday.

"I'll only comment on what a professional, high-character person Geno is, and that he will be sorely missed," Brown said in an email. "Godspeed on a well-deserved retirement."
